We're not talking about creating the universe from scratch, here. We necessarily build near the top of a pyramid of architectures. In the browser, for example, we build on top of JavaScript and the DOM. In many situations, Unix can be seen as the underlying architecture.

Compared to those underlying architectures, most frameworks are ephemeral and indeed "bespoke." JavaScript, DOM, and Unix are specified in standards and have several implementations. They embody decades of shared solutions and conventions.

"It can't be" is a bold claim. "Massive quality advantage" as well. Which frameworks are you talking about exactly?

I think "circular" sort of gets at the point. A circle keeps going round.
